Core i5-6600K + GeForce RTX 3070 Ti Bottleneck Calculator
Whether the Core i5-6600K and the GeForce RTX 3070 Ti hold each other back, at every resolution, with the frame rate you can expect and the single upgrade that fixes it.
- The platform itself is a limit here: an older socket usually means PCIe 3.0 and slower memory, which costs a few percent on top of the figure above.
The same pair at every resolution
A processor pushes roughly the same number of frames whatever the resolution. A graphics card pushes far fewer as pixels go up. That is why the limit moves as you climb this table, and why a bottleneck figure quoted without a resolution means nothing.
| Resolution | Estimated fps | Limited by | Gap |
|---|---|---|---|
| 720p (1280 x 720) | 89 fps | CPU | 20% |
| 1080p (1920 x 1080) | 81 fps | CPU | 6.2% |
| 1440p (2560 x 1440) | 60 fps | Balanced | 0% |
| Ultrawide 1440p (3440 x 1440) | 40 fps | GPU | 11.5% |
| 4K (3840 x 2160) | 24 fps | GPU | 48.7% |
| 8K (7680 x 4320) | 9 fps | GPU | 79.8% |
What to do about it
The Ryzen 7 3700X is the slowest CPU in our database that stops the GeForce RTX 3070 Ti from idling at 1080p (1920 x 1080). A faster chip than that adds nothing at this resolution, so this is the step to buy, not the top of the stack.
